Abstract

This research investigates the heat transfer coefficient as a function of tube position and pressure drop, for in-line tube bank in cross-flow. Experimentation was essentially used to generate log-mean temperature curves and pressure heads upstream and down stream of the test section. The heat transfer and flow parameters such as Nusselt number, Reynolds number, and pressure drop across the bank were calculated. In addition, heat transfer correlations, Nusselt number (Nu) were obtained by power-law curve fitting for each position of the tube in the tube bank. FEMLAB 3.0 was use for numerical simulation and the results obtained compared favourably with that of the experimental results. Numerical results also reveal the important aspects of the local heat transfer and flow features within the tube bank. These characteristics include boundary layer developments between tubes, formation of vortices, local variations of the velocity and temperature distribution.
